Hi, I know this post is from awhile ago but did you ever resolve your weight loss? I believe I went undiagnosed 4 years ago and then was diagnosed three months ago. I took Vancomycin. I initially lost weight and then I changed my diet completely with limited gluten, less dairy, less sugar...so it’s understandable that I lost weight but I have been trying to keep weight on after losing 30 pounds in 3 months. I was overweight though 3 moths ago. So, although the weight loss numerically is not that concerning, I question when the weight loss will stop. I have one very big and lose (often more yellow in color) BM a day. So, the doctor is not concerned but I am. I’m taking a probiotic, eating fermented foods, I can’t take zinc it reignites the Cdiff, but I’m looking for vitamins and would like to see how people maintained weight. I’m also eating a whole avocado a day for fat. I’m just worried. Thank you for any info and for reading.
